The Guardian has a large crossword community that regularly interacts with its crosswords every day, so in March last year we decided to release a mobile crosswords app for Android phones. With the launch of the app we wanted to see whether or not crossword fans would be interested in solving crosswords on a mobile device. Creating this app allowed us to experiment with how we translated our games content to mobile devices and to discover whether we could create a sustainable commercial model for similar products in the future.

The crosswords app originally launched with a free beta trial in March last year and the feedback we received was positive. After the free trial ended, we introduced a number of subscription options as we believed that running an ad-funded app would result in a poor user experience. Unfortunately, since introducing the subscription charge, the uptake has been less than we would have hoped. As a result, we have taken the difficult decision to end our work on, and support for, our Android crosswords app, and it will therefore no longer be available to download from the Google Play store. This also means that there are no longer plans to launch a similar iOS app. We are still considering a future presence on mobile for crosswords, but there is no specific timescale.

What this means for current usersUsers who have already purchased a subscription will still receive all the crosswords they have paid for (one month's worth of crosswords since their latest subscription payment date). However, it will no longer be possible to renew or purchase new subscriptions, or receive new crosswords, after this month is up.

Unless deleted from a user's device, the app will continue to function after the app has been withdrawn from the Google Play store and subscriptions have expired, so that users can complete any outstanding crosswords on the app. However, we cannot promise it will work indefinitely as it will no longer be supported.
